I harp on BMW a lot. Too much, in fact. The automaker still builds machines that provide a truly engaging driving experience. The problem is though, that the lineup has less and less of that. Still, cars like the new M3 and M4 prove that BMW can still create ultimate driving machines.

Back in 2011, however, they may have created their own modern-day masterpiece. It's called the BMW 1 Series M Coupe, or 1M for short. This 335-horsepower mighty mobile proved that BMW had not in fact lost its mojo.

Did they leave a bit on the table with the 1M? I wouldn't have said so back then, but after spending a week with the Dinan S3-R 1M I'm singing a different tune. What Dinan has done is take a great car... and made it into one of the best true driver's cars that I've ever had the pleasure of experiencing.
